I think a coin whose price is still under $ 1 is easier and has a chance to skyrocket 5x in a short time, the coins or tokens include XRP, Cardano, STORM, PRL and so on.
Oyster Pearl (PRL) has been pumped up to 100x, I think this is impossible, but who know. My advice, try to buy a newly completed ICO Token in dex market like forkdelta, but with the provision not yet listed in central market, it is more potential to earn big profits. But you must do research first, because too many scam tokens left by dev
You have a point but you need to be very selective what you buy on forkdelta or etherdelta, there is so much trash there that will never go anywhere, mostly people drop free airdropped coins on these exchanges. Once in a while you can find a hidden gem that goes 100x when listed on another, bigger exchange. But most coins who get launched on ether/fork delta dont make it to another exchange. That is also why they are called the token graveyard. I prefer Kucoin, you find many low cap coins there but they have a brighter future.
